Title: Quantum fundamental groups of 3-manifolds
Abstract: The "quantum fundamental group" of a 3-manifold is a refinement of the fundamental group, defined using isotopy classes of bottom tangles instead of homotopy classes of based loops. It is expected that the QFG plays the role of the fundamental group in Quantum Topology. I plan to discuss the definitions and properties of the quantum fundamental groups and other derived invariants.
